Fourier transform infrared (FTIR) spectroscopy was used to characterize six different underutilized tropical legume seed oils. Intensive discussion on the absorption bands assigned to different functional groups was made. The results showed that wave numbers of many of the bands were independent of the nature of the seed oils while the IR values of bands at 3008 cm^-1 and 1099 cm^-1 were found to be dependent on the nature of the oil. The intensities of the bands of 3008 cm-1, 2922 cm^-1 and 2853 cm^-1 were also found to be function of the composition of the seed oils. https://www.biotech-asia.org/vol3no1a/characteristics-of-legume-seed-oils-by-fourier-transform-infrared-spectroscopy/ Characterization; Legume seed oils; Fourier Transform Infrared
